    Package        : bind9
    CVE ID         : CVE-2024-0760 CVE-2024-1737 CVE-2024-1975 CVE-2024-4076

    Several vulnerabilities were discovered in BIND, a DNS server
    implementation, which may result in denial of service.

    To mitigate CVE-2024-1737 two new configuration statements have been
    added to allow operators of secondary servers and recursive resolvers to
    set an upper bound on the growth of data in their zones or caches.
    Details can be found at:
    https://kb.isc.org/docs/rrset-limits-in-zones

    For the oldstable distribution (bullseye), these problems have been
    fixed in version 1:9.16.50-1~deb11u1. For the oldstable distribution
    (bullseye) the limits to mitigate CVE-2024-1737 are hardcoded and not
    configurable.

    For the stable distribution (bookworm), these problems have been fixed in
    version 1:9.18.28-1~deb12u1.

    We recommend that you upgrade your bind9 packages.

    For the detailed security status of bind9 please refer to its security
    tracker page at:
